Tithing

I’ve read this befuddling statement in a number of books, so I thought I’d respond to it:

Statement read something like: “We should get rid of the concept of tithing and only then will the floodgates of generosity open.”

Issues I have with this:

1.If everyone tithed there would be a lot more good work being done in the world
2.Tithing is a minimum amount you can always give freewill offerings if you feel led
3.I honestly doubt the motives of the people expressing these vantage points. Are they really giving a lot more than if they tithed?

It just smells fishy to say that tithing restricts generosity when the average American Christian gives 2-3% of income.
